A machine is set up to produce items, each with a diameter above 1 inch. The diameters of 15 consecutive items produced are 1.11, 1.15, 0.98, 1.11, 1.08, 1.06, 0.97, 0.97, 1.05, 1.02, 0.98, 0.99, 0.96, 1.03, 1.01. Use a runs test, taking 1 inch as a threshold to test the hypothesis that the measurements represent random deviations from the required standard.
